Objective: The purpose of this study was to compare the hip joint muscle strength of patients with chronic back pain with lumbar instability and normal subjects. Design: A case control study. Methods: Five types of lumbar instability test were conducted on forty young women with chronic low back pain for more than six months, and those who had 3 or more positive tests were selected as subjects. To select chronic back pain patients with lumbar instability group, aberrant movement patterns during lumbar flexion test (FMT), prone instability test (PIT), posterior-anterior mobility test (PAT), passive lumbar extension test (PLE), and pressure bio-feedback (PBF) were applied. In addition, a digital muscle strength meter was used to measure the hip flexor, extensor, adductor, and abductor muscles of chronic low back pain patients with lumbar instability group (n=20) and normal subject group (n=20). Results: As a result of comparing the hip joint muscle strength between the chronic back pain patient group with lumbar instability and the normal group, there were significant differences in the hip extensor, abductor, and adductor muscles (p<0.05). Conclusions: Patients of chronic back pain with lumbar instability were found to have weak hip joint muscle strength. Therefore, this study suggest that include hip joint strength exercise for functional recovery of chronic back pain patients.

The purpose of this study was to evaluate effects of lumbar stabilizing exercise on the functional recovery and the range of motion of low back pain patients. The subjects were consisted of sixty patients who had non specific chronic low back pain(32 females. 28 males; mean aged 37.3) from 19 to 65 years of age(mean age : 37.3). All subjects randomly assigned to the lumbar stabilizing exercise group, the modalities treatment group, the manual treatment group. Lumbar stabilizing exercise group received manual treatment with lumbar stabilizing exercise for 30minutes, modalities treatment group received hot pack used thermal therapy for 20minutes and ICT used electrical therapy for 20minutes and US or MWD used deep thermal therapy for 15minutes, manual treatment group received modalities treatment with therapeutic massage for 10minutes and joint mobilization or manipulation for 10minutes per day and three times a week during 4 weeks period. The Multilevel Roland-Morris Disability Questionnaire(MR-MDQ) was used to measure functional disability level. Visual Analogue Scale(VAS) was used to measure subjective pain level. Remodified Schober test(RST) was used to measure forward flexion range of motion of lumbar segment. Finger-to-Floor test(F-T-FT) was used to measure forward flexion range of motion of full spine of low back pain patients. All measurements of each patients were measured at pre-treatment and 4 week post-treatment. The results of this study were summarized as follows : 1. The MR-MDQ of lumbar stabilizing exercise group, modalities treatment group, and manual treatment group was significantly reduced between pre-treatment and post-treatment(p<.05). 2. The VAS of lumbar stabilizing exercise group, modalities treatment group, and manual treatment group was significantly reduced between pre-treatment and post-treatment(p<.05). 3. The RST of lumbar stabilizing exercise group, modalities treatment group, and manual treatment group was significantly reduced between pre-treatment and post-treatment(p<.05). 4. The F-T-FT of lumbar stabilizing exercise group, modalities treatment group, and manual treatment group was significantly reduced between pre-treatment and post-treatment(p<.05). 5. The results of analyzed effects of MR-MDQ, RST, F-T-FT were significantly reduced (p<.05), but VAS wasn't significantly reduced(p>.05) between treatment type of lumbar stabilizing exercise group and modalities treatment group and manual treatment group according to pre-treatment and post-treatment. 6.

The purpose of this study was to examine the effects of combined respiratory physical therapy on respiratory function, spinal curve and spinal mobility for community-dwelling elderlies with restrictive lung diseases. In total, 10 patients participated in an 8-week intervention program of thoracic cage mobilization and breathing exercise in combination. The results of the study are as follows: for respiratory function, the forced expiratory volume in 1 second (FEV1), forced vital capacity(FVC), and FEV1/FVC were significantly improved to $.30{\pm}0.31{\ell}$, $.46{\pm}.42{\ell}$, and $18.10{\pm}11.39%$, respectively (p<.05). For spinal curve, the thoracic curve and the lumbar curve were improved significantly to $-2.20{\pm}1.40^{\circ}$ and $-1.20{\pm}1.14^{\circ}$, respectively (p<.01). For spinal mobility, the thoracic flexion ($3.40{\pm}2.99^{\circ}$), thoracic extension ($3.50{\pm}1.43^{\circ}$), lumbar flexion ($4.50{\pm}4.74^{\circ}$), and lumbar extension($-1.50{\pm}1.84^{\circ}$) were all significantly improved (p<.05). These findings indicate that thoracic cage mobilization and breathing exercise in combination improve the respiratory function, spinal alignment, and spinal mobility in elderly people with restrictive lung diseases.

The purpose of this study was to compare the effect of heat therapy, stretching exercise and to verify which method was most effective for lumbar flexibility improvement. Subjects were 20 apparantly healthy person(male10, female10) who did not have any medical problem. They were randomly divided and assigned into 2 groups: heat therapy, stretching exercise. For testing flexibility, trunk flexion, bunk extension, and Schober-test were performed. Pre-test was done prior to the each group's treatment. Test was done at 2nd week, 4th week and 6th week. There were no significant difference in improvement of trunk flexion and trunk extension after 6 weeks treatment among 2 methods. However in all 2 groups, there were statically significant improvement in flexibility as time go on. The rate of improvement was highest at 2nd week, while this was attenuated afterwards. The Schober-test score changed significantly from pre-test to the mid-test and to the post-test, while there were no significant difference among 2 methods of treatment. With the results above, it was concluded that heat therapy, stretching-exercise were all effective for improving flexibility without any significant priorities.

It is important to consider lumbar lordotic angle for setup of training program in field of sports and rehabilitaton to prevent unexpected posture deviation and back pain. The purpose of this study was to analyze the biomechanical impact of the level of lumbar lordosis angle during isokinetic exercise through dynamic analysis using a 3-dimensional musculoskeletal model. We made each models for normal lordosis, excessive lordosis, lumbar kyphosis, and hypo-lordosis according to lordotic angle and inputted experimental data as initial values to perform inverse dynamic analysis. Comparing the joint torques, the largest torque of excessive lordosis was 16.6% larger and lumbar kyphosis was 11.7% less than normal lordosis. There existed no significant difference in the compressive intervertebral forces of each lumbar joint (p>0.05), but statistically significant difference in the anterioposterior shear force (p<0.05). For system energy lumbar kyphosis required the least and most energy during flexion and extension respectively. Therefore during the rehabilitation process, more efficient training will be possible by taking into consideration not simply weight and height but biomechanical effects on the skeletal muscle system according to lumbar lordosis angles.

This study is that the elderly female patients having low back pain(34 people) show a change of stabilization ratio after isotonic rehabilitation of 4 types(before exercise, after 4weeks, 8weeks, 12weeks). Under the cover of lumbar extension machine, isometric extension strength and stabilization ratio is measured and analyzed at some flexion angles(the degree of $0^{\circ}$, $12^{\circ}$, $24^{\circ}$, $36^{\circ}$, $48^{\circ}$, $60^{\circ}$, $72^{\circ}$). The conclusion is as follows. 1. The maximum lumbar extension strength at a range of 7 angles have an increase of 73.92% in case of 12weeks isotonic exercise(p<.001). 2. After 12weeks exercise, the lumbar flexion angle maximum extension strength, have an higher increase than 54% on the average at all angles(p<.001). These statistically show a meaningful increase of muscular strength. 3. After 12weeks isotonic exercise, the lumbar stabilization ratio have a decrease of 50.27% at a statistically meaningful level(p<.001). In case of 12weeks exercise comparing with 8weeks, the stabilization ratio decrease at the level of 1.85 versus 1. This figure is similar to that of a normal person. In view of this study, 12weeks exercise for the elderly female patients having low back pain has much influence on the change of lumbar stabilization ratio and this is the scientifically verified result of a long term exercise.

Objectives This study analyzed the correlation between lumbar spine and pelvic body parameters measured using body shape analysis system and X-ray view. Methods Body shape analysis system and X-ray view were performed for 100 patients to diagnose subluxation using body parameters such as pelvic obliquity angle, anterior superior iliac spine to posterior superior iliac spine angle (ASIS-PSIS angle), lumbar lateral flexion angle. The correlation analysis using body parameters obtained through the body shape analysis system and X-ray view was performed by measuring the Pearson correlation coefficient, a parameter test. Results Significant correlations were observed between the values for pelvic obliquity angle, ASIS-PSIS angle, lumbar lateral flexion angle measured by X-ray view and body shape analysis system. The most significant correlation was observed in the value of pelvic obliquity angle. Conclusions Body parameters and posture analysis measured by the body shape analysis system can be used in place of X-ray view. Additional research and samples are still necessary.

Objective : This study aims to examine how lumbar stabilization exercise and resistive exercise affect lumbar and lower extremity muscular strength of the aged. Method : Randomly selected 15 female senior citizens aged 65 or older at S, Y, and J senior citizens' center located in D city who meet the requirements for the study were divided into a resistive exercise group of 7 and a stabilization exercise group of 8 for which 60-minute-exercise sessions were administered three times a week for 12 weeks. Measuring lumbar and lower extremity muscular strength was measured six weeks and 12 weeks after exercise, respectively. Results : First, both resistive exercises and stabilization exercises are effective to improve lumbar muscular strength. Second, resistive exercise is effective to improve flexural muscle strength as well as lower extremity muscular strength, and stabilization exercise is effective for both flexion and extensor muscle strength. Conclusion : The 12 week lumbar stabilization exercise program appeared to be effective to improve lumbar and lower extremity muscular strength of the aged. This indicates that applying this program to identify and prevent frequent risk factors of falling can lead to the prevention of secondary problem factors of falling accidents.
